Show Explanation
Explanation
16. The International Space Station (ISS) completes approximately 16 orbits around the Earth in a single day, traveling at a high velocity of about 17,500 mph (28,000 km/h). At this speed, the station completes one full revolution roughly every 90 minutes. Consequently, astronauts on board witness 16 sunrises and 16 sunsets every 24 hours while maintaining a low Earth orbit at an altitude of approximately 400 km.
